The White Sox added righty Jason Berken to their Triple-A roster, tweets Mark Gonzales of the Chicago Tribune. Berken, 29, tossed 19 2/3 big league innings in 2012, mostly for the Cubs, but was removed from their 40-man roster in October. For the Orioles' Triple-A club, he posted a 3.50 ERA, 6.1 K/9, 2.4 BB/9, and 0.63 HR/9 in 144 innings last year. Four years ago, Baseball America explained that Berken can throw strikes with any of his four pitches, but doesn't have swing-and-miss stuff.

The White Sox also released outfielder Stefan Gartrell, tweets Gonzales. Gartrell had signed a minor league deal with an invite to big league camp. The 29-year-old hit .251/.335/.452 over 472 plate appearances last year for the Braves' Triple-A affiliate.
